Get the crappy Disney Indy, throw out the body and head, put the clothes on a Dragon doll and use the Frontline head, that is imho even better than the toys Mcoy sculpt and you can get him with a nice resin fedora as well:

If anyone needs it painted, feel free to contact me, Iíve done about 200 resin figures and guarantee a life-like finish for a super nominal fee.
